BACKGROUND OF THE INVENTION [0002] The etiology of cancer and other diseases involves complex interactions between cellular factors, including cellular enzymatic receptors and other downstream intracellular factors that relay signals through the intracellular signaling network. Growth factor receptors have been recognized as a key factor in cancer 10 biology, playing a significant role in the progression and maintenance of the malignant phenotype (Jones et al., 2006, Endocrine-Rel. Cancer, 13:545-551). For example, the expression of Epidermal Growth Factor Receptor (EGFR), a tyrosine kinase receptor, has been implicated as necessary in the development of adenomas and carcinomas in intestinal tumors, and subsequent expansion of initiated tumors (Roberts et al., 2002, PNAS, 99:1521-1526). Overexpression of EGFR also plays a role in neoplasia, especially in tumors of 15 epithelial origin (Kari et al., 2003, Cancer Res., 63:1-5). EGFR is a member of the ErbB family of receptors, which includes HER2c/neu, Her2 and Her3 receptor tyrosine kinases. The molecular signaling pathway of EGFR activation has been mapped through experimental and computer modeling, involving over 200 reactions and 300 chemical species interactions (see Oda et al., Epub 2005, Mol. Sys. Biol., 1:2005.0010). [00031 Another critical cellular pathway that is overexpressed by tumors, including mediation of the 20 proliferation of cancer cells, is the insulin-like growth factor (IGF) signaling pathway (Khandwala et al., 2000, Endo. Rev., 21:215-244; Moschos and Mantzoros, 2002, Oncology 63:317-332; Bohula et al., 2003, Anticancer Drugs, 14:669-682). The signaling involves the function of two ligands, IGFI and IGF2, three cell surface receptors, at least six high affinity binding proteins and binding protein protease (Basearga et al., 2006, Endocrine-Rel. Cancer, 13:S33-S43; Pollak et al., 2004, Nature Rev. Cancer 4:505-518). The insulin 25 like growth factor receptor (IGF1R) is a transmembrane receptor tyrosine kinase that mediates IGF biological activity and signaling through several critical cellular molecular networks including RASORAF ERK and P13-AKT-mTOR pathways. A functional IGFIR is required for transformation, and has been shown to promote tumor cell growth and survival (Riedemann and Macaulay, 2006, Endocr. Relat. Cancer, 13:533-43). Several genes that have been shown to promote cell proliferation in response to IGF-l/IGF-2 30 binding in the IGFlR pathway include Shc, IRS, Grb2, SOS, Ras, Raf, MEK and ERK. Genes that have been implicated in the cell proliferation, motility and survival functions of IGFl R signaling include IRS, P13-K, PIP2, PTEN, PTP-2, PDK and Akt. [0004] The signaling interplay between IGF signaling, IGFl receptor and EGFR is important in the regulation of EGFR-mediated-pathway, and can contribute to a resistance to EGFR antagonist therapy 35 (Jones et al., 2006, Endocrine-Rel. Cancer, 13:845-851). [00051 Another pathway that is of interest in the proliferation and control of cancer growth and development includes the Eta family of transcription factors. The Ets family domain proteins, which are defined on the basis of a conserved primary sequence of their DNA-binding domains, function as either -1 WSGR Docket No. 28825.750.601 WO 2009/100159 PCT/US2009/033117 transcriptional activators or repressors, and their activities are often regulated by signal transduction pathways, including MAP kinase pathways (Sharrocks, et at., 1997, Int. J. Biochem. Cell Biol. 29:1371 1387). ETS transcription factors, such as ETS1, regulate numerous genes and are involved in stem cell development, cell senescence and death, and tumorigenesis. The conserved ETS domain within these 5 proteins is a winged helix-turn-helix DNA-binding domain that recognizes the core consensus DNA sequence GGAA/T of target genes (Dwyer et at., 2007, Ann. New York Acad. Sci. 1114:36-47). There is a growing body of evidence that Ets 1 protein has oncogenic potential by playing a key role in the acquisition of invasive behavior of a tumorigenic cell. Among the genes that belong to the Ets 1 pathway to carry out its tumorigenic functions include the matrix metalloproteases MMP-1, MMP-3, MMP-9, as well as urokinase 10 type plasminogen activator (uPA) (Sementchenko and Watson, 2000, Oncogene, 19:6533-6548). These proteases are known to be involved in extracellular matrix (ECM) degradation, a key event in invasion. In angiosarcoma of the skin, Eta 1 is co-expressed with MMP-1 (Naito et al., 2000, Pathol. Res. Pract. 196:103 109). Ovarian carcinoma cells and stromal fibroblasts in breast and ovarian cancer produce MMP-1 and MMP-9 along with Ets 1 (Behrens et al., 2001, 1. Pathol. 194:43-50; Behrens et al., 2001, Int. J. Mol. Med. 15 8:149-154). In lung and brain tumors, Ets expression correlates with uPA expression (Kitange et al., 1999, Lab. Invest. 79:407-416; Takanami et al., 2001, Tumour Biol. 22:205-210; Nakada et al., 1999, J. Neuropathol. Exp. Neurol. 58:329-334). When overexpressed in endothelial cells or hepatoma cells, Ets 1 was shown to induce the production of MMP-l, MMP-3 plus MMP-9, or MMP-1, MMP-9 plus uPA, respectively (Oda et al., 1999, J.

Because of the postnatal developmental and involutional duration, we aimed to investigate normal stiffness values of mediastinal thymus by shear wave elastography (SWE) in different age Hakan Ayyıldız groups of children and discuss imaging findings of thymus. İbrahim Adaletli METHODS We prospectively examined 146 children (90 girls, 56 boys) who underwent a thyroid or neck ultrasound examination. All subjects underwent ultrasound and SWE evaluation of mediastinal thymus by parasternal and suprasternal approach. We grouped the subjects based on age as 0 to 2 months, >2 to 6 months, >6 months to 2 years, >2 to 5 years, >5 to 8 years, and greater than 8 years old. We investigated differences of mean shear wave elasticity (kPa) and shear wave veloc- ity (m/s) values among age groups and the association of SWE values with age, body mass index (BMI), height, and weight of the patients. RESULTS Median and range of age, height, weight, and BMI were 24 months (2–84 months), 85 cm (55– 120 cm), 12 kg (4.55–22 kg), 15.37 kg/m2 (13.92–17.51 kg/m2), 11 cc (2.64–23.15 cc), respectively. Mean shear wave elasticity of thymus of all participants was 6.76±1.04 kPa. Differences of mean elasticity values among the age and gender groups were not statistically significant.

Because of the proximity of the thymus gland to the major mediastinal vascular structure, small thymic lesions often are not detectable on plain chest radiography or conventional tomography. So as a result computed tomography of the mediastinum sho~ld be the imaging procedure of choice ·when thymic pathology is suspected (1). The 10-15% incidence of thymomas in patients with myasthenia gravis has led to routine CT screening of the ·anterior superior mediastinum in many of these patients, especially if these patients recently exacerbated the symptoms. Comput~d tomography also "is r~commended to search for a thymic·carcinoid whenever there is clinical suspicion of ectopic adrencorticotrphic hormone (ACTH) production causing cushing syndrome (2). The presence of thymoma must always be suspected in patients with myasthenia gravis because about 10-15% will have such a tumor (4). Accuracy of radiologic detection of thymoma in association with myasthenia gravis has varied widely (2-7). The evaluations is complicated because fats cpntents of thymus increase with the age- and thymic size is highly variable (8-12). Other method including atteriography (13) Thymic venography (14) Pneumomediastinography (15) ultrasonography (16) and several other methods have been ( 2) found useful in some cases but none of these methods have been ~idely accepted for screening patients with myasthenia gravis.

Materials and methods: We examined 217 patients with thymus-independent myasthenia (n = 42) and thymus-dependent myasthenia, among them patients with thymus hyperplasia (n = 108) and thymoma (n = 67). We used the following methods: ELISA, flow cytometry, light and fluorescence microscopy. Results: Certain genomic (polymorphism of leukocyte HLA-DR antigens) and epigenomic (antibodies to α1 and α7 nAChR subunits, expression of Treg lymphocytes and concentration of cytokines) predictors were identified for various myasthenia phenotypes. The presence of HLA haplotypes DR2 and DR7 in some young patients with M with disease progression led to the development of myasthenia gravis with thymoma (MT) at an older age. The presence of α7 nAChR subunit on thymocyte mitochondria was revealed, which is an additional autoimmune target for autoantibodies in patients with myasthenia gravis.

    THE AMERICAN TOURNAL OF CANCER d A Continuation of The Journal of Cancer Research THE THYMOMA AND THYMIC HYPERPLASIA IN MYASTHENIA GRAVIS WITH OBSERVATIONS ON THE GENERAL PATHOLOGY' E. H. NORRIS, M.D (From the DcpnrtmPnt oj Pathology, Unizlersity of Minnerota) Since the comprehensive study by Bell in 1917 no systematic treatise on the thymic tumors of myasthenia gravis has appeared. It might be expected that the past twenty years would have added the records of many more cases to the literature and have extended our knowledge of the pathological anatomy of myasthenia gravis and the associated thymic tumors. On the contrary but few cases with autopsy findings have been reported and our conceptions con- cerning the morbid anatomy of this disease are much the same as they were in 1917. In the period from 1901, the year in which Weigert published the record of the first case of myasthenia gravis with an associated thymus tumor, to 1917, Bell found published reports of 56 autopsied cases of this disease. He wrote: '' The thymus was described as enlarged in seventeen of these cases; and in ten others it contained a tumor. Therefore some form of thymic involvement seems to occur in nearly half the cases of myasthenia gravis." Since 1917 the records of 6 more autopsies have been published and 5 of these showed thymic lesions. Of the 4 cases to be reported here, 2 had thymic lesions which were recognized. I am of the opinion that pathologic changes may be found in the thymus in cases of myasthenia gravis in direct ratio to the care with which they are sought.
